Abstract

The three-dimensional supramolecular aggregation in the title
hybrid material, (C8H10N5)[H2PMo12O40]2.5CH3OH4H2O, is
based on the formation of O—H O, N—H O and O—
H N hydrogen bonds, and O O and N O electrostatic
interactions (O O = 2.95–3.04 A ˚ and N O = 2.91–3.01 A ˚ ).
Water and methanol solvent molecules make infinite zigzag
belts around the organic cations and Keggin polyoxoanions
with a chain sequence H2O CH3OH CH3OH
CH3OH H2O H2O CH3OH . Each symmetry-unique
water and methanol molecule forms distinct interactions with
the other components in the crystal structure. Five methanol
solvent molecules in the crystal lattice have site-occupancy
factors of 0.5.
